AREA OF THE INVENTION
- BACKGROUND OF THE INVENTION
The invention relates to methods and systems for fitting audio devices, e.g. hearing aids or headsets, to a specific need or desire of a user of such. More particularly the invention relates to an electronic device including a screen, e.g. a conventional computer, which when operatively connected to the audio device can be used to manipulate the settings of the audio device and hence modify the transfer characteristics.
Such electronic devices are well known and are used in connection with most programmable hearing devices.
The complexity of the electronic devices is significant and the complexity is increasing. Therefore there is a need for improvement of such devices in order to achieve devices, which are simpler to handle.
- SUMMARY OF THE INVENTION
The objective of the present invention is therefore to provide a method and a device for use in fitting audio devices, which device while maintaining the required technical capabilities is simpler to handle.
According to the invention the objective of the present invention is achieved by means of the method as defined in claim 1.
By this method it will always be obvious to the user which function is presently being manipulated in the audio device. At the same time the trimmer button may be designed larger and hence enable easier use and still occupy limited space. The significant reduction in trimmer buttons at the same time makes the display simpler and easier to use. The improvement inherently results in a more reliable fitting process and hence increased user satisfaction.
Advantageous embodiments are indicated in claims 2-4.
According to the invention the objective of the invention is likewise achieved by means of the program as defined in claim 5 and being capable of performing the method as mentioned above.
Advantageous embodiments are indicated in claims 6-8.
BRIEF DESCRIPTION OF THE DRAWINGS
In connection with a computer the same advantages as mentioned in connection with the method are hereby achieved.
FIG. 1 is a schematic drawing showing the graphic user interface in a first position of the trimmers where the adjustment of a first area is allocated;
DESCRIPTION OF A PREFERRED EMBODIMENT
FIG. 2 is a schematic drawing showing the graphic user interface in a second position of the trimmers where the adjustment of a second area is allocated.
From FIGS. 1 and 2 a hearing aid appears in connection with fitting equipment adapted to adjust the parameters of the hearing aid. The fitting equipment comprises a computer with a screen, a keyboard and a mouse. The computer runs a fitting software program that is capable of generating control parameters to the hearing aid in order to change settings of this and hereby change the transfer characteristics of the hearing aid.
The software generates an output to the screen. In the FIGS. 1 and 2 four fields A,B,C,D are indicated for manipulating parameters in the hearing aid, the fields indicating areas of low frequencies and soft gain, low frequencies and loud gain, high frequencies and soft gain, high frequencies and loud gain, respectively. A block of trimmers is likewise indicated. The block includes three sets of trimmers, where one of these sets is adapted for manipulating left ear hearing aid, one is adapted for manipulating the right ear hearing aid and the last set of trimmers, the one in the middle, is adapted for manipulating the parameters in both the left and the right ear hearing aid with an identical increase or decrease of the same parameter. This is of course only relevant when two hearing aids are fitted simultaneously.
In FIG. 1 the field A has been activated and the trimmer block is indicated in the position of a first selected field A, hereby indicating visually that this field, or rather the parameter connected to this field, is active. In FIG. 2 yet another field B has been activated and the trimmer block has been moved correspondingly. This gives the person working with the adjustment a very clear and simple indication of what is being done and hence facilitates the process and may reduce the occurrence of errors in the process.
The trimmer block may be allocated to adjust parameters related to more than one field, e.g. by dragging the trimmer block to an area in-between two fields or by pointing between two fields and hence effect the movement of the trimmer block to this area. The trimmer block may then overlap at least part of two or more fields and hereby clearly indicate that the trimmers are active for the fields partly overlapped. This further facilitates the fitting process.
